The Condition Serum was designed to absorb into your skin’s surface almost instantly to support skin rejuvenation on a cellular level. Enhance was developed to allow the healing benefits of the same essential oil combination to linger on your skin’s surface longer. Enhance is especially important to use on the days that you have exfoliated your skin’s surface with Scrub. Enhance is excellent for reconditioning ruff or dry spots like elbows, heels, and cuticles overnight. Use the facial system regularly and support skin health.
